Do you think we are missing an alternative of Accord or a related project?
Accord is a validation library written in and for Scala. Compared to JSR 303 and Scalaz validation it aims to provide the following:
- Composable: Because JSR 303 is annotation based, validation rules cannot be composed (annotations cannot receive other annotations as parameters). This is a real problem with some Scala features, for example
Options or collections. Accord's validation rules are trivially composable.
- Simple: Accord provides a dead-simple story for validation rule definition by leveraging macros, as well as the validation call site (see example below).
- Self-contained: Accord is macro-based but completely self-contained, and consequently only relies on the Scala runtime and reflection libraries.
- Integrated: Other than providing its own DSL and matcher library, Accord is designed to easily integrate with the larger Scala ecosystem, and provides out-of-the-box support for Scala.js, as well as integration modules for Spring Validation, Specs2 and ScalaTest.

Accord is still fairly rudimentary, and there's plenty of improvements to be made:
- The 0.8 milestone lists the planned improvements for the next release.
- Some future plans/ideas:
- Performance benchmarks
- Elide DSL implicit invocations from resulting tree for better performance and smaller code
- Add syntax for custom violation message overrides (e.g.
p.firstName is notEmpty as "no first name!")
- Support custom violation types (e.g.
p.firstName is notEmpty as MyServerError( code = -3 ))
- Full-blown i18n support (need feedback on this)
Ideas and feature requests welcome! You can join the fun on our Gitter channel, report an issue or contact the maintainer directly.
